14. Then you'd better be reading up on HPV-induced cancers.

The 2013 "Annual Report to the Nation on the Status of Cancer" found about 13,000 new cases of oropharyngeal in both men and women linked to HPV in 2009 (the last year of available data), more than 10,500 of which were in men. More than 60 percent of oropharyngeal cancers are caused by HPV, according to the National Cancer Institute, which was an author in the report.

From 2000 to 2009, incidence rates increased for HPV-associated cancer of the oropharynx among white men and women, the report also found.

Previous research found HPV fueled a 28 percent rise in oropharyngeal cancer cases since 1988, amounting for an additional 10,000 U.S. cases each year.

Genden said HPV-related throat cancers are now more common in men than cervical cancer -- which is caused by the same virus -- in women. These cancers are also more commonly found in younger populations, adults between ages 40 and 65, a group typically younger than those affected by smoking-related throat cancers.

People who are developing throat cancer now likely had gotten HPV more than 10 or 15 years earlier, Genden pointed out.
